Construction Details:

• Reinforced polyethylene vapor barrier constructed with virgin resins and UV inhibitors
• Multi-layered extrusion laminated
• Will not grow mold
• Reinforced with a layer of polyester scrim reinforcement to enhance tear resistance and increase service life
• Manufactured in America
• White liners help reduce heat build-up and condensation
• 6 mil Black/White Crawl Space Liner/Barrier is designed simply to keep moisture and gases from entering the crawl space. Not recommended for areas where there will be any activity. Soil compatibility: clay, sand, dirt, mud without rocks or sharp objects
• 6 mil and 10 mil Clear Reinforced Crawl Space Liners/Barriers: work great on foundation walls and grounds where there will be no activity. The 10 mil, DS10HUV liner contains high concentrations of UV inhibitors and thermal stabilizers to enhance outdoor life. Soil compatibility: clay, sand, dirt, mud without rocks or sharp objects
• 10 mil white non-reinforced class 1 and class A: Also works well on foundation walls and grounds where there will be no activity, however not reinforced. Perfect for medium traffic and light storage. High performance features low permeability, excellent tensile strength and strong puncture resistance
• 8 and 12 mil Black/White Crawl Space Liner/Barrier: the 8 mil black/white liner is often used on walls and the 12 mil or 20 mil white liner is often used on floors. When barriers are installed on the walls and floors in this manner it provides great protection to use the crawl space as a root cellar or for storage. Soil compatibility: clay, sand, dirt, mud, rocky soil or soil with tree roots and slightly larger rocks
• 12 mil Antimicrobial Crawl Space Liner/Barrier: 12 mil antimicrobial liner has antimicrobial additives to help prevent the growth of harmful bacteria, fungi, mold, mildew, and algae on or around the liner. It is non-toxic and environmentally safe. Great for use on the walls and the ground in crawl spaces, storage areas and root cellars. (Note: antimicrobial additive is not topically applied, it is mixed in the resin so it is non-migratory) Soil compatibility: clay, sand, dirt, mud, rocky soil or soil with tree roots and slightly larger rocks
• 20 mil White Crawl Space Liner: 20 mil white (on both sides) crawl space liner is the thickest liner with the highest puncture resistance rating in this offering. Great for commercial applications where a heavy-duty liner is required. Also safe for aquaponics applications. UV inhibitors and thermal stabilizers added for extended outdoor lifespan. Soil compatibility: clay, sand, dirt, mud, rocky soil or soil with tree roots, large rocks and broken concrete
• Vapor Bond Tape: Vapor tape bonds to most surfaces creating a waterproof seal and clean appearance. Tape bonds in a wide range of temperatures but it is recommended the tape be in room temperature until ready to use. Cold temperatures can harden the adhesive and make it difficult to stick. Typical installations need 1 roll of bond tape per every 1000 square feet. If the installation has a lot of piers or columns you will need more tape. Roll size is 4 x 180'
• Butyl Tape: Butyl tape is an aggressive reinforced double sided tape. Butyl rubber tape is used to seal the vapor barrier to the foundation walls. It is a non-hardening and flexible and creates a waterproof seal. Butyl tape can also be used to join panels of vapor barrier together by overlapping the seams and applying the tape between the layers. Roll size is 1.5 x 100'
• Christmas Tree Fasteners: Christmas tree fasteners are made of heavy duty nylon and are used to attach the vapor barrier to the foundation wall. The fasteners have a flat white head and a conical tip which gives them a clean, unobtrusive look after installation. In order to carry the weight of the vapor barrier on the foundation, Christmas Tree Fasteners should be installed every 18 - 24. Fasteners are 5/16 diameter x 1-1/8 long and are inserted into a 5/16 hole (a hammer drill work best). Sold in bags of 100 and 500 pieces.

How To Measure Square Footage To Encapsulate A Crawl Space:

• Measure and calculate the following:
  • Measure length of crawlspace
  • Measure width of crawlspace
  • Measure the height of the foundation walls, or as high up on the walls you are going to encapsulation
  • Calculate the perimeter Length of the entire space by adding length + width together and then multiplying by 2. (length + width) x 2.
  • Note: Most crawlspaces are less than 4' tall so using a 4' or 6' wide vapor barrier for the walls will keep the seams to a minimum.
• Calculate Square Footage of the Floor: multiplying length x width
• Calculate Wall Square Footage: Perimeter x Wall Height
